NVIDIA-Certified-Professional Accelerated Data Science 認定 NCP-ADS 試験問題 (Q120-Q125):

質問 # 120
You are comparing the performance of NVIDIA RAPIDS cuML, TensorFlow, and PyTorch for training and inference on a dataset with millions of records.
To design a fair and effective benchmark, which approach should you take?

A. Use only a CPU baseline for comparison to demonstrate the benefits of GPU acceleration, ignoring GPU-specific optimizations.
B. Run each framework on different GPUs to maximize available resources and compare execution times across different hardware configurations.
C. Ensure all frameworks run on the same GPU, use optimized batch sizes, and measure execution time and memory usage with NVIDIA Nsight Systems.

正解：C

質問 # 121
A team of data engineers is working on an Apache Spark-based distributed computing pipeline that leverages NVIDIA GPUs and RAPIDS. They notice that shuffle operations are causing significant slowdowns in performance.
Which optimization strategy should they implement to reduce shuffle impact?

A. Use Spark's default shuffle partitioning without any modification, as GPUs inherently optimize shuffle operations.
B. Store shuffle data in Apache Parquet format on disk for faster access and reduced memory overhead.
C. Disable GPU memory caching to allow automatic CPU-based shuffle optimization.
D. Use RAPIDS Spark-RAPIDS Plugin with GPU-accelerated caching to minimize redundant shuffle operations.

正解：D

質問 # 122
A data engineer is preparing a dataset for training a deep learning model. The dataset contains numerical features with missing values, outliers, and inconsistent units.
Which of the following strategies is the most appropriate for ensuring a standardized and clean dataset?

A. Use the median to fill missing values, convert all numerical values into categorical bins, and apply Min-Max scaling.
B. Remove all rows with missing values and outliers to ensure only clean data is used.
C. Standardize the dataset using the mean and standard deviation, but keep missing values and outliers unchanged to avoid data manipulation.
D. Replace missing values with the mean, apply z-score normalization, and clip extreme outliers based on a threshold (e.g., 3 standard deviations).

正解：D

質問 # 123
You are working on a medium-sized dataset (~500,000 rows, 20 columns) and need to perform fast exploratory data analysis (EDA) with filtering, aggregations, and transformations.
Which of the following Python libraries would be the most efficient choice for this task?

A. PySpark
B. Dask
C. Vaex
D. Pandas

正解：D

質問 # 124
A machine learning engineer is working on an image classification problem where the dataset is small and lacks variability. To improve generalization, the engineer decides to augment the dataset using NVIDIA RAPIDS.
What is the best method to generate synthetic data efficiently while leveraging GPU acceleration?

A. Apply cuML.GaussianMixture() to generate new synthetic data points based on an estimated probability distribution.
B. Use traditional CPU-based augmentation techniques like OpenCV to transform images and generate new data.
C. Use cuDF with cudf.DataFrame.sample() to create new samples by randomly selecting existing rows.
D. Use cuML.PCA() to reduce dimensionality and create synthetic samples by reconstructing the data with added noise.

正解：A
